The electrode (10) contains a protective, electrically insulative web (12) and an electrically conductive adhesive (20 or 24) adjacent one side of the web (12) which is adapted to be oriented to the body. A release liner (18) is placed between the web (12) and the electrically conductive adhesive (20-24) to facilitate removal and placement of an electrical lead wire (14). The biomedical electrode (10) may have a first layer of pressure sensitive adhesive (16) applied between the web (12) and the release liner (18). A second layer of adhesive (24) which is electrically conductive may be positioned adjacent the release liner (18) opposite from the web (12).

Abstract: An apparatus and method for treating one side of a moving web includes a pair of laterally spaced vertical end members. The web to be treated passes in a downwardly extending loop around the lower arcuate edges of the end members and is sealed thereto by tension in the web. The web and end members form a trough containing a flowable treatment material, and the web moves past the flowable material to be contacted and treated thereby. Guide means direct the web downwardly to the inlet side of the trough and upwardly from the exit side of the web-formed trough.

Abstract: Antimicrobial wound dressings are provided comprised of a substrate coated with an antimicrobially effective film of a silver salt. These antimicrobial wound dressings are prepared by vapor coating or sputter coating certain silver salts onto a variety of wound dressing substrates. Preferred silver salts are silver chloride and silver sulfate.

Abstract: This application discloses a method of making high quality color prints by electrophotography. The prints are particularly suited to color proofing. A single photoconductive drum is used together with means to electrostatically charge, laser-scan expose, and toner develop during one rotation. In successive rotations different colored images corresponding to color separation images are assembled in register on the drum. This assembled color image is transferred to a receptor sheet in a final rotation of the drum.

Abstract: A biomedical electrode comprised of an electrical terminal member, an ionically conductive layer, a retainer sheet, a medical tape, first and second release liners, and a protective sheet is provided. The base of the electrical terminal member is disposed between the retainer sheet and the ionically conductive layer so that the retainer sheet prevents dislodging of the terminal upon connection and disconnection of a lead-wire. Also, disclosed is an economical high speed method of manufacturing electrodes.

Abstract: Release coating compositions comprising polysiloxane-grafted copolymer and blends thereof with other polymeric materials on sheet materials and the back side of adhesive tapes are provided. Controlled and predictable release is achieved through variation of the number and the length, e.g., the molecular weight, of polysiloxane grafts in the copolymer.

Abstract: Optical fibers coated with a blend of poly(vinylidene fluoride) and at least one other polymer are poled to make the coating piezoelectric, whereby the optical fiber will undergo strain when the coating is exposed to an electric field.

Abstract: Composite prelaminated tape for forming closures for disposable diapers comprising a pressure-sensitive adhesive fastening tape partially overlying a release tape and a unifying strip bridging an edge of the release tape and the adjacent portion of the fastening tape. In use, the fastening tape and the release tape are bonded permanently to opposite sides of one edge of the diaper, the end of the fastening tape overlying the release tape being thereafter lifted free from the release tape and adhered to the opposite edge of the diaper from which it can be respectively reused and re-adhered to the edge of the diaper.

Abstract: The present invention relates to microporous materials incorporating a nucleating agent and methods for making the same.

Abstract: An improved roadway sign comprising a light retroreflective indicia region and colored retroreflective background region is provided. The retroreflective properties of the regions are selected such that the ratio of the retroreflective brightness of the indicia to that of the background is substantially larger at observation locations within the legibility zone for the sign, than the ratio is at observation locations outside the legibility zone. The sign is conspicuous by virtue of the bright retroreflection and distinctive color of the background outside the legibility zone, yet is legible because of the increased contrast ratio of the indicia to the background in the legibility zone.

Abstract: An externally worn body device adapted to be magnetically held supercutaneously with a case being separable into first and second parts and being releasably secured together. The case contains a magnetic device for magnetically holding the case in a supercutaneous position with the magnetic field strength at the surface of the case adjacent to the supercutaneous position being adjustable. The magnetic device may also be adjustable in magnetic polarity. The externally worn body device may contain a transmitting coil positioned within the case for transmitting an electrical signal intended for transcutaneous reception. The externally worn body device may be combined with an implanted subcutaneous member which contains a magnetic device for providing an appropriate magnetic attraction to the corresponding supercutaneous magnetic device.

Abstract: A pressure-sensitive adhesive that has high cohesive strength and adheres permanently to high-solids automotive paint systems preferably comprises a mixture of (1) a crosslinked acrylic copolymer of acrylic acid ester and N-vinyl-2-pyrrolidone, and (2) certain tackifier resins. Useful tackifier resins are poly(isobornylmethacrylate), pentaerythritol ester of rosin, and mixed-aliphatic/aromatic polymeric tackifier resins such as a t-butylated styrene. The tackifier resin preferably has a T.sub.g of at least 30.degree. C., M.sub.n from 300 to 3000, and a solubility parameter from 8 to 9. The novel pressure-sensitive adhesive is particularly useful as a dense surface layer of a composite tape having a foamlike core.

Abstract: A process for making ceramic spheriods by mixing and converting spheroids, with the aid of water, raw materials of 50-99.8 parts by weight mineral particulate (e.g. blend of orthoclase, nepheline, hornblende and diopside) which particulate includes at least one mineral having chemically bound water or sulphur in a form which is not substantially water soluble and in amounts sufficient to yield 0.5 to 5 weight percent water or 0.04 to 2 weight percent sulphur in the total mass; 0.1 to 50 parts by weight silicon carbide; and 0.1 to 15 parts binder. The wet spheroids are dried and the dry spheroids are fired in contact with a parting agent (e.g. aluminum oxide) for a sufficiently long time to form a shell containing parting agent on the ceramic mineral having a fired density of less than about 2.9 grams per cubic centimeter when fired above 1,100.degree. C. The binder is typically bentonite clay.
